Overview
DX Engineering Glass Antenna Insulators
Sometimes the oldest stuff turns out to be the best. Our exclusive DX Engineering Glass Antenna Insulators hearken back to the earliest years of "wireless" transmissions.
Because Irish ship builders of the day pronounced "double" as "dooble," these insulators were once known as "glass doobies" due to their tempered-glass material and double-ended form. Glass insulators offer the highest of electrical insulation properties, strength and resilience available in any insulator of its size. There will be no signal bleed off with these little glass wonders!
DX Engineering's DXE-TGI-2 end insulators are 3.69 in. long with 1.125 in. diameter double ends. Each smoothed and rounded end has a 5/16 in. (0.3125 in.) hole that will accommodate many wire and rope sizes without chafing. Their tensile strength and resistance to arcing will withstand almost any wire-antenna use within the Amateur Radio service, domestic or abroad. Since these are end insulators, they are sold as a pair.
These are not toy-like models or replica insulators; these are fully functional, high strength glass insulators with excellent RF properties! But, that is not to say that they aren't gorgeous and worthy of showing off! They certainly are perfect for display as a radio room decoration or as a living area conversation piece. Very smooth and pleasing to the touch, these are attractive glass insulators that make a fantastic gift for the ham who thought he had everything!
Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. In this instance, some interesting information on "Glass Doobies."
Bring back a bit of the essence of the Amateur Radio of yesteryear in your wire antenna construction. These glass insulators are actually quite striking in their appearance. Order DX Engineering Glass Antenna Insulators and gain the benefits of using a material that has provided the best wire-antenna insulation for more than a century!
